1 Claim.

This invention appertains to new and useful improvements in fruit comminuting devices and more particularly to a novel grater and. shredder particularly adapted for domestic use.

An important object of the invention is to provide a compact and inexpensive grater and shredder of a portable nature.

Another important object of the invention is to provide a domestic type grater and shredder wherein the object treating blades are quickly interchangeable.

These and Various other important objects and advantages of the invention will become apparent to the reader of the following specification.

In the drawings:

Figure 1 represents a front elevational View of the device.

Figure 2 represents a rear elevational view of the device. a

Figure 3 represents a vertical sectional view through the machine.

Figure 4 represents a fragmentary top plan view showing the coupling between the shafts and one of the smooth treating places.

Figure 5 represents a front elevational view of the grater wheel.

Figure 6 represents a fragmentary front elevational view of the shredder wheel.

Figure 7 represents a back elevational view of the grater wheel, the back of the shredder wheel being of the same construction.

Referring to the drawings wherein like numerals designate like parts, it can be seen that the combined device consists of the base 5 having the narrow upright 6 merging into the relatively Wide back wall 7. The short bottom wall 8 extends from one side of the back wall 1 and merges with a pair of relatively wide side walls 9-9, these side walls 9-9 each connected by the front wall N, which at close intervals is provided with inwardly punched portions defining pointed abut-- ments or protuberances ll.

Hingedly connected to the short bottom wall 8 is the closure l2 which operates between the lower edges of the side walls 99 and meets the lower edge of the front wall ID as in the manner substantially shown in Figure 3.

A neck portion I3 rises from the upper portion of the back wall I and is provided at its upper end with the hand loop l4 whereby the machine can be very readily and conveniently carried.

The back wall 7 has an opening I5 therein through which the shaft l6 extends, this shaft being provided with a crank I! and handle l8 at its outer end and with a lug 9 at its inner end. The stop collar 28 on the shaft limits inward 5 movement of the shaft l6, abutting the back side of the wall 1 in the manner shown in Figure 3 and being held in this position by the elongated strip spring 2| which is anchored at its lower end as at 22 while its upper end is slotted as at 23 to receive the shaft l6.

The spring 2| thus holds the lug end of the shaft H6 in the slotted tubular socket 24 on the back side of the shredder wheel 25, which shredder wheel is provided with V-shaped cutting elel5 ments 26 on the front side thereof. The wheel 25 is thus held by the shaft against the front wall It! as shown in Figure 3.

The grater wheel 21 is of the same construction as the shredder wheel 25 with the exception that the projections on its working side are small projecting studs 28 to perform the necessary grating action in cooperation with the protuberances H on the front wall It.

While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size, materials may be resorted to without departing from the spirit and scope of the invention as claimed 30 hereinafter.

Having described the claimed is:

A combination utensil of the character described comprising a receptacle, a shaft disposed through one wall of the said receptacle, the opposite wall of the receptacle being provided with protuberances on the inner side thereof, a plate on the inner end of the shaft, having protuberinvention, what is ances on the side thereof opposed to the wall 5 having protuberances, a fixed collar on the shaft outside of the receptacle, and a strip spring secured at one end to the receptacle and tensionally engaging the collar at its opposite end to urge the plate against the opposite wall of the receptacle, said strip spring being provided with an elongated slot therein for receiving the said shaft.
